Buying advice

Choose a lock that fits your laptop's security slot (Kensington compatible is standard). Keyed locks are simplest but can be lost; combination locks avoid keys but codes can be forgotten. Consider cable length and build quality: thicker steel cables are harder to cut. For MacBooks, get a dedicated wedge lock. If you travel light, an ultralight model may be best. Always check reviews for reliability of the locking mechanism.
